Clashes broke out last Thursday night after an Eritrean migrant was hurt by a bullet on the A16 motorway between Calais and Boulogne. The Pas de Calais prefecture spokesman told Channel 4 News there was no connection between this incident and last night’s confrontations.

Some estimates say that up to 2,500 migrants – mainly Afghan, Sudanese, Eritrean and Syrian – live in camps around Calais, from where most hope to move on to the United Kingdom.
